WILLIAM C. I-IEDGCOCK, OF

CHICAGO, ILLINOIS, ASSIGNOR TO AMERICAN STEEL FOUNDRIES, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

CAR-TRUCK PEIDESTAIJ.

To all whom t may concern.'

Be it known that I, WILLIAM C. HEDG- coox, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Truck Pedestals, of which the following is a specication.

My invention relates to car trucks of the pedestal type and has particular `reference to a novel uniting means for the lower ends of said pedestals. A similar construction is shown in my Patent No. 1,143,707, filed of even date'. herewith.

In the use of the usual trucks having pedestals, the journal boxes and springs are received between the two jaws of the pedestal, the lower ends of the jaws being secured together by a tie strap extending from one pedestal to the other and usually bent up at its ends and attached to the truck frame. This tie strap is secured to the lower ends of the pedestal jaws by means of short bolts, one to each jaw. The journal box with its contained parts reciprocates between the pedestal jaws and in starting or stopping quickly one or the other of these jaws must absorb the inertia of the box, axle and wheels. Owing to the fact that the bolts which secure the strap to the lower ends of the jaws are loose either at the time of application or shortly thereafter, the two jaws of each pedestal do not operate in conjunction to absorb the inertia of the contained parts and the blow is therefore taken up by one or the other of the jaws depending on the direction of travel of the truck. Therefore it is common for the pedestal to be broken at some point usually at the angle of joinder of the top transverse portion thereof. My invention seeks to overcome these diiiiculties and to provide means whereby the lower ends of the pedestal jaws shall be rigidly though removably united.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

partly in section showing a pedestal constructed in accordance with my invention; Fig. 2 is a bottom plan view thereof, and, Fig. 3 is a fragmentary side elevation.

Referring more particularly to the drawings it will be seen that the pedestal may comprise upper horizontal member 10, and depending jaws 11, 12. The lower ends of these jaws areV united by means of a bar 18, and the usual tie strap 141-, the ordinary strap being used with the apertures 15, therein, as is usual. The bar 13, is provided with dowels 16, Vwhich project upwardly through the aperture 15, in the strap and through a similar aperture in the lug 17, on the lower end of the jaws. The bar 13, is enlarged as at 18, and a transverse pin 19, is passed through an aperture in the enlargement and engages apertured ears 20, projecting downwardly from the pedestal jaws. If desired the enlargement 18, may be transversely apertured to register with an aperture in the bolt 19, and a key or cotter pin 21, inserted therethrough. It will be seen that by the use of the construction referred to the lower ends of the pedestal are securely locked together and any force transmitted to one of the jaws is shared by the other jaw.

I claim:

l. In a cartruck, the combination of a pedestal having jaws, a tie strap and a bar, said strap and bar serving to close the opening between said jaws, said bar, strap and jaws being interlocked whereby the lower ends of the jaws are securely tied together, substantially as described.

2. In a car truck pedestal including in combination, depending jaws, a tie strap and a bar, said bar having portions which serve to interlock the parts, and pins engaging said strap and said jaws and removably uniting the jaws, substantially as described.

WILLIAM C. HEDGCOCK.
